A study was made of anthropometric measures (body mass, length of the body, circumference of the head, circumference of the chest) in infants borne to women in separate primi-, secundi-, or multipara events in those areas of the Krivoy Rog industrial region arbitrarily taken as relatively pure (unpolluted) and those affected by radioactive contamination, with ages of the child-bearing women being 18-25, 26-30, and greater than 30 years old. Newborn babies from the contaminated district of the city were found to have higher anthropometric values. There was a persistent augmentation of the circumference of the chest in newborns from the contaminated district, which fact suggests development of adaptive processes in the fetus during the intrauterine development under conditions of contaminated atmosphere of the industrial region.
The content of essential and toxic elements, except beryllium and mercury, in the hair of examined children (girls aged 7-9 years) is within the biologically acceptable levels set by WHO. The data on the content of essential trace elements suggest that urgent measures aimed at normalization of the elemental status of children are required.
The conditions and dynamic changes of the most important indices related with population health in a number of Northern regions of the Russian Federation are under discussion. A conclusion is made that they are predetermined by migration processes, latitude effects and peculiarities of production activity.
Nanotechnologies find wide application in industry and medicine. The Russian market of nanotechnologies is at the very beginning of development. Rospotrebnadzor has amassed a wealth of experience in the creation of efficacious systems for estimation and sanitary-epidemiological control of the safety of goods and foodstuffs. The assessment of the safety of nanoparticles and nanomaterials has been carried out since 2007. In 2008-2009, a survey was initiated with a view to developing safety criteria for nanoproducts, nanomaterials, and nanotechnologies. In 2010, research institutions of Rospotrebnadzor were engaged in investigations aimed to develop relevant regulatory and procedural documentation. Studies are underway to work out new highly sensitive methods for the detection, identification and qualitative determination of nanomaterials in the environment, food-staffs, and biological media.
Negative pollution effects from atmospheric discharges by aluminium facilities exerted on population health can be traced by the parameters of the reproductive function in women, physical development of newborns, general and differential morbidity of children aged below one year as well as by anthropometric signs in birth, morbidity of children and adults, mortality, including due to oncology. The introduction of modern technologies including the preliminarily fire anode treatment and the use of highly effective methods of purification of industrial wastes cut the concentration (in atmospheric air) of anhydrous hydrogen fluoride and of solid fluorides as well as of aluminium to maximum permissible concentration; it also essentially reduced the content of benzapilene. A better atmospheric air observed yet in the course of renovation contributed to a lower morbidity of children, aged below one year, as well as to the prevalence of diseases affecting the eyes, respiratory and digestive organs, skin and subcutaneous cellular tissue; it also cuts the number of congenital anomalies versus the data obtained in a neighboring district.
A prospective cohort study was conducted to examine lipid metabolic parameters in 5-14-year-old children. A directional trend was established in lipid parameters (a reduction in the level of total cholesterol and a change in its fractional composition: higher levels of high-density lipoprotein cholesterol with a parallel decrease in the concentration of low-density lipoprotein cholesterol), which is due to age-related features. There was a change in the spread of deviations in cholesterol exchange parameters from the standard values with age.
Classes B and C medical waste is of particular concern since it is an epidemiological and toxicological hazard. Predisinfection of Class B medical waste with the chemicals that have different toxicity levels, as well as further burial in the urban landfill were a reason for defining its hazard classes by biotesting in order to establish the possibility of additional environmental pollution. Class B (epidemiologically hazardous) medical waste was ascertained to be little dangerous and indangerous to the environment. The findings show it necessary to develop an integral waste hazard index that would reflect the whole spectrum of its negative impact on the environment and human health.
The paper deals with trends in climate change in the Omsk Region: the increases in average annual air temperatures and rainfall, which are attended by the higher number of abnormal weather events, as shown by the data of the Omsk Regional Board, Russian Federal Service for Hydrometeorology and Environmental Monitoring. There is information on weather severity in 2008: there was mild weather in spring and severe weather in winter, in January in particular. A survey of physicians has revealed that medical workers are concerned about climate problems and global warming and ascertained weather events mostly affecting the population's health. People worry most frequently about a drastic temperature drop or rise (as high as 71%), atmospheric pressure change (53%), and "when it is too hot in summer (47%).
The publication is the third fragment of the multiparameter study. The level and causes of genome instability and sensitivity are assessed in children living in Magnitogorsk, a city with one of the largest mills in Russia. The city is in the list of the world's 35 most polluted ones. A transverse retrospective analysis found no differences in primary morbidity among 5-7-year-old children who had been living in different districts of Magnitogorsk since birth and were going to municipal kindergartens located adjacent to their house. Contrary to the expectations, the prevalence of morbidity and diseases that were markers for an industrial town was significantly lower among the children residing in the settlements situated around the mills than that in the city's other districts. There were 9 organic compounds that had no hygienic standards, the content of which in the snow samples collected in the areas of the examined kindergartens correlated with the prevalence of the children's morbidity. Family social and living conditions were shown to affect the children's morbidity.
The specific features of enteric and nasopharyngeal microbiocenoses and the species composition of bifidobacteria have been studied in children living in the industrial towns of the Irkutsk Region under the existing anthropogenic load. Ambient air pollution is characterized and a presumptive human health risk assessed.
Interloci equilibrium between pairs of gene markers in the samples of different health rate in the population of Buryats of Chitinskaya Province was tested. The following methods were used: calculation of interloci correlation coefficients, chi 2-testing of the hypothesis of interloci equilibrium and the modification of principal components analysis on the basis of the matrix of Pearson's coefficients of contingency. In the groups of "extreme" health rate the tendency to increase in interloci disequilibrium was discovered. The reason for this effect is the increase in some phenotype combination frequencies that can be considered as markers of non-specific individual resistance in the environmental condition of the populations studied.
The article deals with clinical results of medical examination and treatment of children residents of industrial districts in Sverdlovsk area, with various methods of analysis determining relationships between heavy metals, metalloids and marker anamnestic data and hematologic abnormalities (changes in RBC, platelets and reticulocytes counts).
A comprehensive study of the state of urban soils revealed the altered structural and functional organization of microbiocenosis versus that of the soils of intact forest ecosystems. The indicator microbial and biochemical parameters of the state of the soils under urban technological pressure were identified. The findings may be used to evaluate the natural environment, to make an urban environmental monitoring.
The immune status of Moscow dwellers was studied. The findings indicate the criterion significance of immunological and allergological parameters in the estimation of a risk of allergic diseases under the influence of poor environmental factors influence. Hyperactivity in individuals with high immunoglobulin class E levels to environmental factors is suggested by the elevated concentrations of serum specific IgE to intrahouse factors that in combination with the increased levels of anti-inflammatory cytokines (interferon-gamma, tumor necrosis factor-alpha) and the suppressed production interleukin-4 are criteria for the early manifestations of allergy.
The lifestyle of schoolchildren in a large industrial town was studied in relation to the residence (industrial and administrative areas) and the type of an education establishment (general education schools and innovative education establishments). The spread of lifestyle defects (sleep and walk irregularities, inactivity, bad habits, employment) was shown to be higher in the schoolchildren living in the industrial areas, in general education school pupils in particular. That of lifestyle defects was higher in girls (sleep and diet irregularities, inactivity) than in boys. The findings provide evidence that there is a need for a differential approach to molding a healthy lifestyle in schoolchildren, by keeping in mind the environmental and socioeconomic situation of a residence, the type of an education establishment, age, and gender.
The purpose of the study was to assess the sanitary-and-hygienic state of solid garbage (SG) burial grounds in the Perm Territory in different stage of a life cycle. This paper presents the results of the study of deposited waste, forming dump soil, and SG ground emissions by general sanitary and sanitary-microbiological parameters and their effect on environmental objects. The performed studies of the sanitary-and-hygienic situation on some grounds of the Perm Territory suggest that there is a need for setting up a system for sanitary-and-monitoring of SG ground and for elaborating engineering, organizational, and prophylactic measures to assure the sanitary-and-hygienic safety of objects and to control the quality and quantity of waste to be buried and the currents of emissions (ground body degassing, filtrating sewage drainage and purification).
The established tense environmental situation in Krasnouralsk, Sverdlovsk Region, presents a serious threat to human health. Development of a medium-term municipal environmental program for a Krasnouralsk urban district provides solutions of environmental problems. The human health status and carcinogenic and non-carcinogenic risks from exposure to chemical substances polluting ambient air, drinking water, and soil have been assessed within the framework of the program. The findings have served as a basis for elaborating technological and sanitary-and-hygienic measures of the environmental program to assure human environmental safety.
